AJEROPLANE.

Application filed July 28,

.ments in aeroplanes and has, for its principal object to provide a structure which offers the least resistance in passing through the air and uses the currents of air to assist in the buoyanc of the aeroplane, while flying and to deve op energy for electric or other motors.

Another very important object of the mvention resides in the provision of an aerolane having a'body constructed with tubuar members extending longitudinall thereof and propellers mounted in the rout of the tubular members and turbines in the rear portions thereof.

A still further very important object of the invention resides in the provision'of an aeroplane of this nature, which is comparatively simple in its construction, thoroughly eiiicient and reliable in operation, easy 'to manoeuvre and otherwise well adapted to the purpose for which it is designed. I

.A still further very important object of this invention resides in the provision of using current of air through tubes, when plane is flying, to drive turbines coupled with electric generators or other devices furnishing power for forward engines.

- With the above numerous other objects in view, as will appear as the descriptions proceed, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings Figure l is a top plan of an aeroplane embodying the features of our invention, showing portions thereof broken away.

Figure 2 is a longitudinal vertical section therethrough.

Figure 3 is a front elevation thereof.

Figures a and 5 are diagrammatic front elevations showing different forms of tubes which may be use Figures 8 and 7 are diagrammatlc longitudinal views of tubes showingdifferent turbine structure which may be 'used.

Figure 8 is a view similar to Figure 1 showing a generator, and

Figure}? is a longitudinal section therethrou h.

Be'erring to the drawings in detail, and especially the embodiment shown in Fi res 1 to 3, inclusive, it will be seen that the pdy of the aeroplane comprises a longitudinal 1927. Serial No. 209,044.

central portion 5 having vertical passages 6 therethrough, and a pair of tubes 7 one to. each side of the central portion 6, extending longitudinally thereof. Wings 9 project lat erally from the body, one to each side thereof and have tubular passages 10 extending longitudinally therethrough. In the front of each tubular member 7 there is mounted a prime mover 11, for operation of a propeller 12. In the rear portion of each tubular side member 7 of the body, thereis formed a de-v pression 14, in the bottom, and a shaft 15 is journaled so that, blades 16 coupled with generator move in the depression 14 and in the passage through the tubular member. Figure 6 it is shown that the tubular members 7 may be flared at their front ends and in the rear have the turbines, both at the top and at the bottom in suitable compartments for that purpose. In Figure 7 it is shown englnes. Y

11 Figure 4., it is shown that the ortions of the body may be circular. In igure 5 it is shown that the body members may be oval shaped and the wing structures may be formed'of a plurality of cylindrical tubes.

It will be seen that an aeroplane constructed in accordance with this invention will bear little resistance to flying through the air and the arrangement of the propellin means in the tubular portion of the body wi greatly assist in the forward propulsion thereof.

In the vertical passages 6 of the central portion 5 .it will be seen that the propellers 20 are mounted for assistin in liftin the aeroplane from the groan and whi e in flight.

In Figures 8 and 9 we have shown an embodiment of the invention ver similar to that included in Figure 1, but in the center haveshown a generator 30 operated by a propeller 31. I

It is thou ht that the construction, operation, and a'vantages of this invention will now be quite apparent without a more detailed description thereof. It will be seen that the principles of the invention may be embodied in ground vehicles and in boats. The present embodiment of the invention has been disclosed in detail, merely by Way of example, since inu actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction and in the combination and arrangement of parts may be resorted to, without departing from the spirit or scope of the invention'as hereinafter claimed. or sacrificing any of its advantages.

' Having thus described the invention, what we claim is 1. In an aeroplane, a bod comprising a pair of longitudinally extending tubular side members, the bottoms of which adjacent their rear ends are depressed, to form compartments and turbines journaled in the side members so that their blades move longitudinally of the side members and in the compartments, being actuated by currents of air through the side members.

2. In an'aero lane, a bed pair of longitudinally extendin mbers comprising a tubular side the bottoms of which adjacent their rear endstare depressed, to form oom partments and turbines journaled in the side members so that their blades move lon tudinally of the side members and in t e compartments, being actuated by currents of air through' the side members, propeller gieans in the forward ends of the side memers.

3. In an aeroplane, a body pair. of longitudinally extending tubular side members, the bottoms of which adjacent their rear ends are depressed, to form com partments and turbines journ'aled in the side members so that their blades move longitudinally of the side members and in the compartments, being actuated by currents of air through the side members, propeller means in the forward ends of the side mem= hers, a central member between the side member and formed with vertical passages, and propellers in the vertical passages In testimony whereof We 11 our sia= tures.
